UPDATE: Warner Bros. And The MPAA Remove New Hangover Part II Trailer From Theaters

We all would have been disappointed in the trailer for The Hangover Part II if it hadn't pushed the envelope a little, and director Todd Phillips didn't disappoint-- the green-band trailer that debuted last week featured cursing, pig blood splattered over the inside of a car, and the phrase "when the monkey nibbles on the weenus, it's funny in any language." You might have wondered how they got away with all of that in a trailer approved for all audiences, and now it seems the MPAA is asking themselves the same thing. Movie theater owners received today a notice from Warner Bros. to remove the trailer from its spot in front of Source Code; the studio didn't even send a replacement trailer and said in the notice that "Warner Bros. and the MPAA have instructed all theaters to remove" the trailer.

You can see the notice for yourself at Slashfilm, where a helpful reader passed along a photo. It also claims that the next Hangover Part II trailer will be #3B (the one being removed is #2) and will show up in front of Scream 4, which opens next Friday. Of course, none of this changes the fact that the original Hangover II trailer is still online, including in glorious HD at Apple. So exactly who are Warner Bros. and the MPAA trying to protect from this trailer, and what are they so freaked out about? There's been no official comment yet from Warner Bros., so in the meantime we'll just be dying for an explanation.

UPDATE:THR has received an official statement from Warner Bros. regarding the pulled trailer. They say, "In our haste to meet the placement schedule for this trailer, we failed to properly vet the final version with the MPAA. We acted immediately to correct the mistake and removed the trailer from screens."

UPDATE 2: The guys at JoBlo say that the trailer may not have been pulled and edited for content. Apparently it's headed back into theaters, but in front of only rated-R movies this time.
